Global Warming Revisited

I have not written on this subject for a while. The Presidential election preoccupied almost everyone, including me. Now the we have a new administration which claims to be more aligned with Al Gore's position on global warming which could lead to policies that directly affect us it seems an appropriate time to bring this issue back to the forefront. Here is a link to a minority report issued by the U.S. Senate Committee on Environment and Public Works. The subtitle on the web page says: More Than 650 International Scientists Dissent Over Man-Made Global Warming Claims.

Here are excerpts from the web page explaining the background of this report.

Over 650 dissenting scientists from around the globe challenged man-made global warming claims made by the United Nations Intergovernemntal Panel on Climate Change (IPCC) and former Vice President Al Gore. ... The over 650 dissenting scientists are more than 12 times the number of UN scientists (52) who authored the media-hyped IPCC 2007 Summary for Policymakers.

The chorus of skeptical scientific voices grow louder in 2008 as a steady stream of peer-reviewed studies, analyses, real world data and inconvenient developments challenged the UN and former Vice President Al Gore's claims that the "science is settled" and there is a "consensus." On a range of issues, 2008 proved to be challenging for the promoters of man-made climate fears. Promoters of anthropogenic warming fears endured the following: Global temperatures failing to warm; Peer-reviewed studies predicting a continued lack of warming; a failed attempt to revive the discredited “Hockey Stick”; inconvenient developments and studies regarding CO2; the Sun; Clouds; Antarctica; the Arctic; Greenland; Mount Kilimanjaro; Hurricanes; Extreme Storms; Floods; Ocean Acidification; Polar Bears; lack of atmosphieric dust; the failure of oceans to warm and rise as predicted.

In addition, the following developments further secured 2008 as the year the “consensus” collapsed. Russian scientists “rejected the very idea that carbon dioxide may be responsible for global warming”. An American Physical Society editor conceded that a “considerable presence” of scientific skeptics exist. An International team of scientists countered the UN IPCC, declaring: “Nature, Not Human Activity, Rules the Climate”. India Issued a report challenging global warming fears. International Scientists demanded the UN IPCC “be called to account and cease its deceptive practices,” and a canvass of more than 51,000 Canadian scientists revealed 68% disagree that global warming science is “settled.”

This new report issued by the Senate Environment and Public Works Committee's office of the GOP Ranking Member is the latest evidence of the growing groundswell of scientific opposition challenging significant aspects of the claims of the UN IPCC and Al Gore. Scientific meetings are now being dominated by a growing number of skeptical scientists. The prestigious International Geological Congress, dubbed the geologists' equivalent of the Olympic Games, was held in Norway in August 2008 and prominently featured the voices of scientists skeptical of man-made global warming fears.


Skeptical scientists are gaining recogniction despite what many say is a bias against them in parts of the scientific community and are facing significant funding disadvantages. Dr. William M. Briggs, a climate statistician who serves on the American Meteorological Society's Probability and Statistics Committee, explained that his colleagues described “absolute horror stories of what happened to them when they tried getting papers published that explored non-‘consensus’ views.” Briggs, in a March 4, 2008, report, described the behavior as “really outrageous and unethical behavior on the parts of some editors. I was shocked.”

During the last and previous glacial periods there were temperature and carbon dioxide up-trends and downtrends. Credible data from Vostok and EPICA showing these trends are readily available. Close examination of these data shows unequivocally that on many occasions temperature trended down for centuries while carbon dioxide level was higher than it had been during a prior temperature uptrend. This shows that, at least at that time, temperature was not driven by carbon dioxide level.

It is well known that added increments of carbon dioxide have less influence than previous increments. This has been elucidated using the added-blankets metaphor. Since there is more carbon dioxide in the atmosphere today than during the glacial periods, added increments of carbon dioxide today have even less influence than they did during the glacial periods when they did not drive temperature. Thus added atmospheric carbon dioxide today does not drive temperature and AGW that is based on increased atmospheric carbon dioxide is a mistake.
